High-coverage Internet of Vehicles roadside unit deployment method and system, medium and application

Abstract

The invention belongs to the technical field of Internet of Vehicles deployment in an expressway scene, and discloses a high-coverage Internet of Vehicles roadside unit deployment method and system, amedium and an application. An expressway is segmented, and the middle point of each segment of the expressway is used as a candidate deployment point of RSUs. When a new RSU needs to be deployed eachtime, the network coverage rate of the RSU deployed is calculated at each candidate deployment point by using an Internet of Vehicles coverage rate calculation method, a roadside unit is placed on the candidate deployment point capable of maximizing the Internet of Vehicles coverage rate, and steps are repeated until all RSUs are deployed. For the characteristics of long Internet of Vehicles distance, few RSU nodes, high vehicle speed, frequent topological change and the like in an expressway scene, the invention provides a low-complexity and efficient RSU deployment method. When RSUs are deployed beside the expressway, a road is segmented, the RSU deployment position is optimized, and the high coverage rate of the Internet of Vehicles is achieved.

Description

technical field [0001] The invention belongs to the technical field of vehicle network deployment in expressway scenarios, and in particular relates to a high-coverage vehicle network roadside unit deployment method, system, medium and application. Background technique [0002] At present: With the development of intelligent networked vehicles and Internet of Things technology, vehicles are no longer just means of transportation consisting of controllers and actuators. Vehicle-to-vehicle interconnection and vehicle-road coordination have become the best choices to improve the efficiency of automobile travel and reduce the rate of automobile accidents. The Internet of Vehicles composed of On Board Unit (OBU) and Road Side Unit (RSU) has become the mainstream target of future urban traffic and vehicle upgrades. In the Internet of Vehicles scenario, the movement of vehicles is restricted by the road topology, and the diversity of road structures and the high-speed movement of ...

AI Technical Summary

Problems solved by technology

[0006] The difficulty in solving the above problems and defects is: the highway distance is long, and due to the possible accumulation of vehicles on the highway, if the traditional uniform deployment of RSUs is adopted, the RSUs may be idle for a long time in areas with sparse vehicles, resulting in waste of resources. However, the use of RSU in areas where vehicles gather produces queues, data congestion, etc.
